Your home’s exterior is constantly exposed to the elements—rain, wind, UV rays, pollution, moss, algae, and more. These forces not only affect the way your home looks but can also compromise its structural integrity and long-term value.
Whether you’re a homeowner in London or anywhere in the UK, maintaining the exterior of your property isn’t just about kerb appeal. It’s about protecting your investment, ensuring safety, and preventing expensive repairs down the line.
In this comprehensive guide, we’ll take you through:
- Why exterior maintenance is essential
- How power washing works
- What surfaces to focus on
- Seasonal care checklists
- Eco-friendly cleaning options
- DIY vs professional cleaning
- How to choose the right contractor
- FAQs and actionable maintenance tips
Why Exterior Maintenance Matters
1.1 First Impressions Matter
They say you never get a second chance to make a first impression. When it comes to property, the exterior is what sets the tone—whether you’re welcoming guests or potential buyers.
1.2 The UK Climate Challenge
Rain, damp, and frost accelerate wear and tear. North-facing walls gather moss, while shaded areas can develop algae and mould quickly. Exterior neglect in the UK can lead to costly repairs.
1.3 Structural Protection
Proper maintenance can stop small issues—like clogged gutters or cracked render—from escalating into major problems such as foundation damage or water ingress.
1.4 Kerb Appeal and Property Value
According to estate agents, a well-maintained exterior can increase your property value by 5%–10%. Clean driveways, sparkling windows, and moss-free roofs attract buyers instantly.
What is Power Washing?
Power washing, or pressure washing, uses high-pressure water jets to remove dirt, moss, algae, lichen, mould, and grime from surfaces.
2.1 How It Works
A powerful motor pumps water at high pressure through a nozzle, blasting away debris. Some units include heating or detergents for enhanced cleaning.
2.2 Soft Washing vs Pressure Washing
- Soft Washing: Uses low pressure + chemicals – ideal for delicate surfaces like roofs or render.
- Pressure Washing: High pressure, water only – great for patios, driveways, and hard surfaces.
2.3 Common Uses
- Driveway cleaning
- Patio and block paving cleaning
- Roof moss removal
- Brick and stone cleaning
- Gutter and fascia washing
Surfaces That Need Regular Cleaning
3.1 Driveways
Oil stains, tyre marks, moss, and dirt build up quickly. Block paving, concrete, and tarmac can all benefit from pressure washing.
Tip: Re-sand block paving joints post-cleaning to prevent weed regrowth.
3.2 Patios & Pathways
Green algae and black spots not only look bad but can also be slippery.
Cleaning Frequency: Every 6–12 months depending on shade and use.
3.3 Roofs
Roofs collect moss and lichen, which absorb moisture and can damage tiles.
Best method: Soft washing with biocide treatment. High pressure can cause leaks.
3.4 Walls and Render
Discoloured render can make even a new home look aged. Use low-pressure or soft washing to restore vibrancy.
3.5 Decking & Timber
Wooden decking becomes slippery and discoloured over time. Power washing restores the grain and improves safety.
Seasonal Maintenance Checklist
Season | Tasks |
Spring | Power wash patios, check for mould/algae, clean windows, repair cracks |

Eco-Friendly Exterior Cleaning
With growing awareness around environmental protection, modern power washing includes:
5.1 Eco Detergents
Use biodegradable, pH-neutral solutions that break down naturally. Always check labels for “safe for pets and plants.”
5.2 Water Conservation
Commercial machines now use up to 30% less water than traditional hoses.
5.3 Wastewater Management
Professional services ensure that runoff does not enter public drains illegally, adhering to UK Environment Agency guidelines.
Common Exterior Problems (and Solutions)
Problem | Cause | Solution |
Moss on roof | Damp + poor sunlight | Soft washing + biocide |
Algae on render | Humid weather | Soft wash with anti-fungal agent |
Oil-stained driveway | Vehicle leaks | Degreaser + hot water pressure wash |
Slippery decking | Algae buildup | Low-pressure wash + wood treatment |
Block paving weeds | Lack of jointing sand | Pressure wash + re-sanding |
